[Qemu-devel] [Bug 1779634] [NEW] qemu-x86_64 on aarch64 reports "Synchronous External Abort"

[He Yi]

Public bug reported:

Purpose: to run x86_64 utilities on aarch64 platform (Intel/Dell network 
adapters' firmware upgrade tools)
System: aarch64 server platform, with ubuntu 16.04 (xenial) Linux 
4.13.0-45-generic #50~16.04.1-Ubuntu SMP Wed May 30 11:14:25 UTC 2018 aarch64 
aarch64 aarch64 GNU/Linux

Reproduce:
1) build linux-user qemu-x86_64 static from source (tried both version 2.12.0 & 
2.11.2)
   ./configure --target-list=x86_64-linux-user --disable-system --static 
--enable-linux-user

2) install the interpreter into binfmt_misc filesystem
   $ cat /proc/sys/fs/binfmt_misc/qemu-x86_64
     enabled
     interpreter /usr/local/bin/qemu-x86_64
     flags:
     offset 0
     magic 7f454c4602010100000000000000000002003e00
     mask fffffffffffefefcfffffffffffffffffeffffff

3) packaging Intel/Dell upgrade utilities into docker images, I've published 
two on docker hub:
   REPOSITORY          TAG
   heyi/dellupdate     latest
   heyi/nvmupdate64e   latest

4) run the docker container on aarch64 server platform:
   docker run -it --privileged --network host --volume 
/usr/local/bin/qemu-x86_64:/usr/local/bin/qemu-x86_64 heyi/dellupdate:latest

5) finally, within docker container run the upgrade tool:
   # ./Network_Firmware_T6VN9_LN_18.5.17_A00.BIN

Errors: in dmesg it reports excessive 'Synchronous External Abort':

kernel: [242850.159893] Synchronous External Abort: synchronous external abort 
(0x92000610) at 0x0000000000429958
kernel: [242850.169199] Unhandled fault: synchronous external abort 
(0x92000610) at 0x0000000000429958

thanks and best regards, Yi
